What this handbook is for

ponishfom is a plain-English reference for people choosing, fixing or leaving a UK mobile service. Every network chapter follows the same ten sections, so you can compare like with like instead of wading through marketing pages.

We publish no prices — they change weekly and go stale faster than any website can follow. What we publish is the part that doesn't change: how each network is structured, what its policies actually mean, where it's strong, where it's weak, and the exact steps for switching, fixing, complaining and staying safe.
